The phrase “singing off the wall,” referring to singing from projected words rather than a hymn book, first appeared in Canadian Mennonite in 2010. This image shows that the practice went back much further. Stirling Avenue Mennonite Church in Kitchener, Ont., recently donated a collection of glass “lantern slides” probably in use circa 1924-45. This particular slide of the hymn “Blessed Assurance” was created by the United Church Publishing House in Toronto. The donation also included several “radio mat” templates which a congregation could use to create its own slides, thus dazzling youth or Sunday school singing times, Christmas programs or budget meetings with new technology.
